RICHMOND, Texas (AP), Jun 20 - A father-son duo from South Texas showed no handicap when they stepped up to a par-3 tee and each shot a hole-in-one on Father's Day.

Lonnie Whitener, 57, told the Houston Chronicle (http://bit.ly/13VlAHF ) that his 115-yard drive using a gap wedge on the sixth hole at River Pointe Golf Club in Richmond struck the flag stick and dropped in the hole.

Then, up stepped 13-year-old Zach Whitener, whose shot from 100 yards using a 6-iron landed near the pin and gently rolled in.

The U.S. Golf Association does not keep records of holes-in-one, but the National Hole-in-One Registry says the chances of two players acing the same hole in the same round are one in 17 million.
